Update: October 25, 2018

In 2019/2020, the King County Road Services Division will perform roadway preservation repairs and drainage improvements along approximately three (3) miles of NE Old Cascade Highway that was damaged by a storm in 2011. This storm created flooding, changed the course of the East Fork Miller River and washed out approximately 160 linear feet of NE Old Cascade Highway, resulting in the permanent closure of the historic Miller River Bridge #999W to vehicular traffic.

King County Road Services Division is planning on constructing the following improvements:

  • Construct a new cul-de-sac turnaround on the west side of the East Fork Miller River on NE Old Cascade Highway at Miller River Road NE
  • Construct a new hammerhead shaped turnaround on the east side of the East Fork Miller River on NE Old Cascade Highway
  • Remove the short span Cascade Scenic Highway Bridge #999X over a tributary stream as well as its east and west approaches between Miller River Rd NE and the East Fork Miller River
  • Replace six culverts
  • Stabilize a steep slope/slide area
  • Improve approximately 3,300 linear feet of roadside ditches
  • Repair, chip-and-seal approximately three miles of the entire roadway
